The porous nature of a lava rock is ideal for absorbing essential oils. With no need for water or electricity, these diffusers are the perfect choice for desktops, nightstands, hotel rooms, and travel use. The Lava stones are a type of pumice shaped into uniform discs that are incredibly porous, meaning there are lots of air pockets for oils. Lava diffusers work by allowing the oil to evaporate slowly.

Add three to four drops of desired oil to lava rock. Refresh with additional drops of oil as desired.
